PRODUCT SAFETY SERVICING GUIDELINES

FOR BLU-RAY DISC PLAYER PRODUCTS

IMPORTANT SAFETY NOTICE

This manual was prepared for use only by properly trained audio-video service technicians. When servicing this product, under no circumstances should the original design be modified or altered without permission from LG Corporation. All components should be replaced only with types identical to those in the original circuit and their physical location, wiring and lead dress must conform to original layout upon completion of repairs.

Special components are also used to prevent x-radiation, shock and fire hazard. These components are indicated by the letter “x” included in their component designators and are required to maintain safe performance. No deviations are allowed without prior approval by LG Corporation. Circuit diagrams may occasionally differ from the actual circuit used. This way, implementation of the latest safety and performance improvement changes into the set is not delayed until the new service literature is printed.

CAUTION : Do not attempt to modify this product in any way. Never perform cus-

tomized installations without manufacturer’s approval. Unauthorized modifications will not only void the warranty, but may lead to property damage or user injury.

Service work should be performed only after you are thoroughly familiar with these safety checks and servicing guidelines.

GRAPHIC SYMBOLS

The exclamation point within an equilateral triangle is intended to alert the service personnel to important safety information in the service literature. The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the service personnel to the presence of noninsulated “dangerous voltage” that may be of sufficient magnitude to constitute a risk of electric shock. The pictorial representation of a fuse and its rating within an equilateral triangle is intended to convey to the service personnel the following fuse replacement caution notice: CAUTION : FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ALL FUSES WITH THE SAME TYPE AND RATING AS MARKED NEAR EACH FUSE.

SERVICE INFORMATION

While servicing, use an isolation transformer for protection from AC line shock. After the original service problem has been corrected, make a check of the following:

FIRE AND SHOCK HAZARD

1. Be sure that all components are positioned to avoid a possibility of adjacent component shorts. This is especially important on items trans-ported to and from the repair shop.

2. Verify that all protective devices such as insulators, barriers, covers, shields, strain reliefs, power supply cords, and other hardware have been reinstalled per the original design. Be sure that the safety purpose of the polarized line plug has not been defeated.

3. Soldering must be inspected to discover possible cold solder joints, solder splashes, or sharp solder points. Be certain to remove all loose foreign particles.

4. Check for physical evidence of damage or deterioration to parts and components, for frayed leads or damaged insulation (including the AC cord), and replace if necessary.

5. No lead or component should touch a high current device or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces must be avoided.

6. After reassembly of the set, always perform an AC leakage test on all exposed metallic parts of the cabinet (the channel selector knobs, antenna terminals, handle and screws) to be sure that set is safe to operate without danger of electrical shock. DO NOT USE A LINE ISOLATION TRANSFORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms per volt or more sensitivity in the following manner: Connect a 1500 ohm, 10 watt resistor, paralleled by a .15 mfd 150V AC type capacitor between a known good earth ground water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC voltage across the combination of 1500 ohm resistor and .15 mfd capacitor. Reverse the AC plug by using a non-polarized adaptor and repeat AC voltage measurements for each exposed metallic part. Voltage measured must not exceed 0.75 volts RMS. This corresponds to 0.5 milliamp AC. Any value exceeding this limit constitutes a potential shock hazard and must be corrected immediately.

TIPS ON PROPER INSTALLATION

1. Never install any receiver in a closed-in recess, cubbyhole, or closely fitting shelf space over, or close to, a heat duct, or in the path of heated air flow.

2. Avoid conditions of high humidity such as: outdoor patio installations where dew is a factor, near steam radiators where steam leakage is a factor, etc.

3. Avoid placement where draperies may obstruct venting. The customer should also avoid the use of decorative scarves or other coverings that might obstruct ventilation.

4. Wall- and shelf-mounted installations using a commercial mounting kit must follow the factory-approved mounting instructions. A product mounted to a shelf or platform must retain its original feet (or the equivalent thickness in spacers) to provide adequate air flow across the bottom. Bolts or screws used for fasteners must not touch any parts or wiring. Perform leakage tests on customized installations.

5. Caution customers against mounting a product on a sloping shelf or in a tilted position, unless the receiver is properly secured.

6. A product on a roll-about cart should be stable in its mounting to the cart.

Caution the customer on the hazards of trying to roll a cart with small casters

across thresholds or deep pile carpets.

7. Caution customers against using extension cords. Explain that a forest of extensions, sprouting from a single outlet, can lead to disastrous consequences to home and family.

SERVICING PRECAUTIONS

CAUTION: Before servicing the BLU-RAY DISC PLAYER covered by this service data and its supplements and addends, read and follow the SAFETY PRECAUTIONS. NOTE: if unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions in this publications, always follow the safety precautions. Remember Safety First :

General Servicing Precautions

1. Always unplug the BLU-RAY DISC PLAYER AC power cord from the AC power source before:

(1) Removing or reinstalling any component, circuit board,

module, or any other assembly.

(2) Disconnecting or reconnecting any internal electrical

plug or other electrical connection.

(3) Connecting a test substitute in parallel with an electro-

lytic capacitor.

Caution : A wrong part substitution or incorrect polar-

ity installation of electrolytic capacitors may result in an explosion hazard.

2. Do not spray chemicals on or near this BLU-RAY DISC PLAYER or any of its assemblies.

3. Unless specified otherwise in this service data, clean electrical contacts by applying an appropriate contact cleaning solution to the contacts with a pipe cleaner, cotton-tipped swab, or comparable soft applicator.

Unless specified otherwise in this service data, lubrication of

contacts is not required.

4. Do not defeat any plug/socket B+ voltage interlocks with whitch instruments covered by this service manual might be equipped.

5. Do not apply AC power to this BLU-RAY DISC PLAYER and / or any of its electrical assemblies unless all solidstate device heat sinks are correctly installed.

6. Always connect the test instrument ground lead to an appropriate ground before connecting the test instrument positive lead. Always remove the test instrument ground lead last.

Insulation Checking Procedure

Disconnect the attachment plug from the AC outlet and turn the power on. Connect an insulation resistance meter (500V) to the blades of the attachment plug. The insulation resistance between each blade of the attachment plug and accessible conductive parts (Note 1) should be more than 1Mohm. Note 1 : Accessible Conductive Parts include Metal panels, Input terminals, Earphone jacks,etc.

Electrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static” can generate electrical charges sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate an electrical charge sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil,or comparable conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed.

Caution: Be sure no power is applied to the chassis or cir-

cuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Normally harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device.)

5-10. Aspect Ratio

The customer has bars on the top and bottom of the screen, the left and right of the screen, or both.

Is the movie

wide screen or

full screen?

YES

What is the aspect

ratio of the DVD disc

being played?

YES

What is the aspect

ratio of the BD player

set at?

YES

What is the resolution

of the BD player set at?

A full screen movie played on a wide screen TV will have bars

on the left and right side of the TV. The customer needs to

make sure they choose the appropriate type of movie

they want to view.

If the aspect ratio is 1.33:1 then the movie is set up for full screen

viewing. Bars will appear on the left and right side of the screen

if the TV is wide screen. If the aspect ratio is 1.85:1 or 2.35:1,

then there will be bars on the top and bottom as that ratio is

bigger than widescreen TVs (1.78:1).

Make sure the BD player aspect ratio is set to

the appropriate setting, depending on the aspect ratio of the TV.

If the customer chose 4:3 Letterbox, then bars will appear on the top

and bottom. The customer can choose the panscan setting to

get rid of the bars.

Try changing the resolution to 576p. 720p, 1080i and

1080p resolution require a widescreen aspect ratio which

means bars will be placed on the left and right side for

full screen movies.

YES

What is the aspect ratio of

the television set at?

Make sure the aspect of the television is set appropriately.

If the aspect ratio of the television is set at 4:3 when the TV

5-11. My Unit Won’t Upconvert

The customer has a problem with getting the unit to change resolutions to 576p, 720p, 1080i, or 1080p.

Is the disc

currently playing?

YES

Is the customer using

component (red, blue,

and green) cables?

YES

Is the customer using

any sort of adapter cable?

YES

Is the customer using

an HDMI or DVI cable?

Ask the customer to press stop to stop the disc from playing.

Ask the customer to press the resolution button to change the resolution.

The BD player will not change resolutions while the disc is playing.

Discs with copy protection will not upconvert above 576p

when using component cables. The component output does not have

HDCP (highbandwidth digital content protection) compliancy

which causes the BD player to switch from 720p or 1080i to 576p.

RGB to DVI or RGB to HDMI adapters will not upconvert.

RGB outputs and inputs are not HDCP compliant. If the customer

sees an error message about HDCP, this is the issue.

Copy protected discs will not upconvert

when HDCP is not found on the input or output.

Regular discs can convert to 1080p over the HDMI output and

only the HDMI output. The TV has to have HDCP compliancy on

the HDMI input. The display has to accept the resolution

(576p, 720p, 1080i, or 1080p).

YES

Is the customer using an

HDMI to DVI cable?

YES

Has the customer tried

multiple discs?

Some movie companies will not allow their discs to upconvert

past 576p. If only one disc poses a problem, then the issue is the disc.

The customer will need to try multiple discs.

One disc not upconverting means the disc may not upconvert. Some movie companies will not allow their discs to upconvert.

If multiple discs display the issue, remove the disc and change

The Quality indicator during movie retrieval corresponds to the following bandwidth requirements:

• 1 dot is 0.5 Mbps

• 2 dots is 1.0 Mbps

• 3 dots is 1.6 Mbps

• 4 dots is 2.2 Mbps

Do you have adequate

broadband connection speed

YES

Do not have any other online

activity on your network

YES

Test your bandwidth

We recommend a minimum connection speed of 1.5Mbps.
